An update on the migrant caravan in Mexico, tackling global loneliness, and creating empathy with poet Kwame Dawes

Today on the show, we explore a global problem that you may not even realize is a problem: loneliness. Also, we have an update on the caravan of migrants moving through Mexico that Trump tweeted about so much a few weeks ago. And, host Carol Hills talks about race in America with Kwame Dawes, who was born in Ghana, raised in Jamaica, and now teaches at the University of Nebraska-Lincoln.
